Objective: Comparison in vitro the superficial roughness of two Bulk Fill resins using two polishing systems of abrasives rubbers: JOTA® (Switzerland) (aluminum oxide, silicium carbide and silicone) and Optimize® (TDV) (Germany) (silicone- aluminum oxide). Materials and methods: Were used 60 resin specimens of resin divided in four groups G1: Tetric-N Ceram® Bulk Fill (Ivoclar Vivadent, USA)/ polishing system JOTA®( Switzerland), G2: Tetric-N Ceram® Bulk Fill (Ivoclar Vivadent, USA)/polishing system Optimize® (TDV) (Germany), G3: Aura Bulk Fill (SDI, Brazil) / polishing system JOTA® (Switzerland) y G4: Aura Bulk Fill (SDI, Brazil) / polishing system Optimize® (TDV) (Germany). All the specimens were made in a metal matrix (6mm x 4mm), were the resins were inserted with a resin spatula (TNCIGFT2 Hu Friedy), and fotoactivated with a lamp Elipar LedTM (3M-ESPE), with an intensity of 1200 mW/cm2. Immediately, the initial roughness of all groups is measured with the Roughness meter Mitutoyo SJ-210P (China). Subsequently, the polishing was executed out with the two rubber systems according to each group, and the final roughness was measured. Results: Statistically significant difference was found on the roughness of G1. This is even greater than all the groups evaluated, and that the smallest difference was in the G2 group. A statistically significant difference was found when comparing the two resins with the polishing systems evaluated. Conclusions: The surface roughness found in the evaluation of Bulk Fill Tetric-N Ceram® Bulk Fill (Ivoclar Vivadent, USA), with the JOTA® (Switzerland) polishing system presents the lower roughness than Aura Bulk Fill resin (SDI, Brazil) with the two polishing systems evaluated.
